the used Krauß extension for computing the vehicles’<br />
longitudinal movement were taken by implementing an API<br />
for embedding other car-following models. Some initial<br />
implementations of other models exist, though not all of<br />
them are able to deal correctly with multi-lane urban traffic.<br />
What is already possible to do with car-following models is<br />
also meant to be implemented for lane-change models.<br />
B. Model Improvements<br />
While evaluation of academic driver behavior models is<br />
one of the aimed research topics, most models are<br />
concentrating to describe a certain behavior, e.g.,<br />
spontaneous jams, making them inappropriate to be used<br />
within complex scenarios which contain a large variety of<br />
situations. In conclusion, next steps of SUMO development<br />
will go beyond established car-following models. Instead, an<br />
own model will be developed, aiming on its variability<br />
mainly.<br />
C. Interoperability<br />
SUMO is not the only available open source traffic<br />
simulation platform. Some other simulators, such as<br />
MATsim, offer their own set of tools for demand generation,<br />
traffic assignment etc. It is planned to make these tools being<br />
usable in combination with SUMO by increasing SUMO’s<br />
capabilities to exchange data. Besides connecting with other<br />
traffic simulation packages, SUMO is extended for being<br />
capable to interact with driving or world simulators. Within<br />
the DLR project “SimWorld Urban”, SUMO is connected to<br />
the DLR driver simulator, allowing to perform simulator test<br />
drives through a full-sized and populated city area.<br />
VII. SUMMARY<br />
We have presented a coarse overview of the microscopic<br />
traffic simulation package SUMO, presenting the included<br />
applications along with some common use cases, and the<br />
next development steps. The number of projects and the<br />
different scales (from single junction traffic light control to<br />
whole city simulation) present the capabilities of the<br />
simulation suite. Together with its import tools for networks<br />
and demand and recently added features such as emission<br />
modeling and the powerful TraCI interface, SUMO aims to<br />
stay one of the most popular simulation platforms not only in<br />
the field of vehicular communication. We kindly invite the<br />
reader to participate in the ongoing development and<br />
implement his or her own algorithms and models. Further<br />
information can be obtained via the project’s web site [2].<br />
